PADLOCK.

- Toall 'whom 'it may concern:

Be it known that I, FRANK M. MERRILL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Padlocks, of which the following is a specification.

This invention relates to padlooks, `and particularly to atype of padlock shown and described in a previous a plication of mine filed May 13, 1907, Seria No. 373,512,and the object of the present invention is to improve the construction of such a padlock, and particularly the mechanism which di.- rectly operates upon the shacklefor locking or unlocking the shackle.

The accompanying drawings illustrate the invention, and referring 'thereto:-Figure 1 is a front elevation of the padlock, the upper portion of which is shown in section to illustrate the construction of the parts relating to the present invention. Fig. 2 is a cross section through the padlock on line zfz Fig. 1. Fig. 3 is a perspective view in detail of the cam disk. Fig. 4 is a perspective view in detail ofa sliding bolt.

1 designates the case of the padlock which is provided near each edge with longitudinal sockets 2 and 3, and the sockets 2 and 3 receive legs 4 and 5 respectively of a shackle 6. The shackle leg 5 'is the longer leg and is always enga ed in the socketl 3, while the shorter leg 4 1s adapted to be raised out of its socket 2 when the shackle is pulled out. Each leg 4 and 5 is provided with a notch 7. The case 1 is also formed with a central longitudinal cylindrical pocket 8 parallel with sockets 2 and 3 but which does not extend through the top wall of the case. The case 1 1s bored transversely near its upper end to form two sockets 9 which are in line with each other, and communicate with, and are radial of the pocket 8, and which respectively intersect with the sockets 2 and 3. Each transverse socket 9 is bored with two diameters to form a shoulder 10.

Mounted in each socket 9 is a slidin bolt 11, Shown ,in/detail in Fig. 4, each s iding bolt 11 being provided with a attened end 12 from lwhich rojects a stud 13. The

other end of the olt 11 is provided with a ange 14, and'a lug 15 is formed be ond the flange 14. When the shackle 6 is c osed the lugs 15 of the bolts 11 respectively engage notches 7 of the shackle and thus lock the shackle securely in position. A coil com- Specication of Letters Patent.

pression spring 16 is arranged between each flange 14 and the yadjacent shoulder 10, the spring 16 serving to operate against flange 14 and move the bolt outwardly.

Revolubly mounted in' the upper end of pocket 8 is a'cam disk 17, shown in detail 1n Fig. 3, the cam disk being provided with a stem 18 and with two depending studs 19 arranged diametrically opposite each other. The studs 19 coperate with key controlled mechanism, not necessary to herein show or describe, for operatin the cam disk 17. The cam disk 19 is :provided with two Vcam slots 20 which respectively receive studs 13 of the sliding bolts 11.

By turning the cam disk 17 .the cam slots 20l act upon studs 13 tol draw the sliding bolts 11 inward and thus withdraw lugs 15 from notches 7 in the shackle and thus release the shackle, the shackle springing out to clear the short leg 4 assoon as it is released, and the shackle when thus open prevents the bolts 11 from being projected outwardly by springs 16 for the reason that the round portion of leg 5 acts as an abutment for the adjacent lug 15, and thus holds theadjacent sliding bolt from moving outwardly, which bolt through the medium of the intermediate cam disk 17 holds its mate from being thrust outward by its s ring 16. When, however, the shackle is pus ed back closed, as soon as the notch 7 in leg 5 is brought into register with the adjacent lug 15 the sliding bolt is thrust out by its spring 16 and the lug 15 enters the notch 7 of leg 5. Simultaneously the notch 7 in le 4 receives the lug 15 of its adjacent sliding oit. As both sliding bolts are thrust outward by their springs their studs 13 acting in the cam slots 2O turn the cam disk .17 to normal osition, and the padlock is then locked. T e flattened portions 12 of the sliding bolts 11 slide over the face of the cam disk 17 and bearing flatly against the cam disk prevent the sliding bolts from having any revoluble movement. lThe present construction is superior to the construction shown in the former application referred to in that itis easier to construct the two transverse sockets in line with each other than to drill them slanting and parallel with each other. Moreover as the two sockets 9 are not parallel with each other, but are in alinement, the width of the upper portion of the case 1 which contains the sliding bolts may be narrower and may be curved to conform tol the cross sectional outlinel of the main body of the case 1, as indicated inv Fig. 2, thereby making it much easier to nish and polish the case 1.A

What I claim is v L A padlock com rising a case having two shackle sockets, a s ackle with itslegs received in said sockets, each of the shackle legs having a locking'notch', a pair of sliding-bolts in line with each other and provide with lugs adapted to en a e in the respective notches in the shac e egs, a cam vdisk provided with cam'slots, and means on the slid-- l.ing bolts engaging in the cam slots.

2. A padlock com rising a case having two shackle sockets, a s ackle with its legs received'in said sockets,` each ofthe shackle legs, having a locking notch, a 'pair of sliding bolts in line with eachother and provided with lugs adapted to engage in the resplective notches in the shackle legs, the case aving transverse sockets in alinement with each with a shoulder, Op@ of Said- Sliding bolts in f other and intersecting with the shackle sockets, each transverse socket being formed each transverse socket, and having a flange, a colled sprlng 1n each transverse socket be-l 'shackle sockets, a s ackle with its legs rev-A ceived in said sockets, each leg having a lock-' transverse'sockets ing notch, the case hav' in alinement with each ot er and intersecting with the shackle sockets, a sliding bolt ineach transverse socket and` formed with' a flattened end and with a lug on'the other end adapted to engage anotch in theshacklev leg, a cam disk under the flattened ends. of the sliding bolts and'havinghtwo cam slots, 4a

stud on each'bolt projecting into a ca'rn slot, l the cam disk having a stem and adapted ,to

be operated by keymechanism.

In testimony whereof, I have herentoset my hand at'Los Angeles,Califo-rn ia, this 15th 'I day of August, 1907. Y
